Hello friends, I have this refrigerator with freezer that has always been the same since I have it: Freeze it until it becomes a solid block and unplug it to defrost. The issue is that he began to walk a few days well after cleaning and just defrosts without starting to make ice, I tried to disconnect and is doing well for a while and returns to the same. The engine is running, it has gas, we already made two charges after fixing losses, it is a saccol 863 old original engine
